Miguel Cabrera led the Tigers (1-2) with a pair of singles before getting hit by a pitch in the sixth inning.

He was diagnosed with a contusion on his right hand but X-rays came back negative.

Tigers starter Spencer Turnbull (0-1) allowed three runs on four hits over five innings of work, with five strikeouts.

Daniel Norris and Victor Alcantra combined for three innings of scoreless relief for Detroit.

McKinney opened the scoring in the fourth inning with a hit to right field. Although he was gunned down by Detroit right-fielder Nicholas Castellanos trying to stretch the hit into a double, it was more than enough time for Toronto third baseman Brandon Drury to score for a 1-0 lead.

Smoak added to that lead two batters later, sending a 2-2 pitch from Turnbull into the Blue Jays bullpen. The homer brought home Teoscar Hernandez, who had walked in the previous at-bat. It was Toronto's first home run of the season.

Giles took over from Biagini in the ninth inning, striking out Christin Stewart. He then gave up a sharply hit single to Grayson Greiner before inducing a popfly to centre field by Dustin Peterson.

A strikeout-put out of Gordon Beckham ended the game and gave Giles his first save of the season.
